Hi,<br><br>After some testing I've found out that my client's hardware recognizes DTMF only if digits are sent 50ms apart with 50ms of tone duration. This was tested using a test device which generates DTMF.<br><br>
Now asterisk doesn't do it by default because digits going out from Asterisk are not being recognized.<br><br>Using command sendDTMF, I can control inter-digit duration, and using toneduration I can control duration of tone per digit. But I can't find a way to do both at the same time<br>
<br>Application sendDTMF simply ignores the value set in toneduration and sends DTMF at some default value, which I don't know what it is, but it is obviously not 50ms because the hardware can't reliably recognized the digits.<br>
<br>Is there a way I can send digits with 50ms tone duration and 50ms gap between them?<br clear="all"><br>-- <br>Zeeshan A Zakaria<br>
